Info - How to setup Vizzu

In HTML, create a placeholder element that will contain the rendered chart.

<html>
 <body>
  <div id="myVizzu">
  </div>
 </body>
</html>

In JavaScript, initialize and configure the chart:

import Vizzu from 'https://cdn.jsdelivr.net/npm/vizzu@0.7/dist/vizzu.min.js'
import {
    data
} from 'https://lib.vizzuhq.com/0.7/assets/data/music_industry_history_1.js'

let chart = new Vizzu('myVizzu')

chart.initializing

chart.animate({
    data
})

This is a 2-step animation:

1st: set the Split parameter to true

2nd:

  • move the Measure to the X-axis
  • set the Align parameter 'center'
  • set the Split parameter to false
  • arrange the markers in reverse order
  • switch the Geometry from Area to Rectangle
chart.on('plot-axis-label-draw', (event) => {
    let year = parseFloat(event.data.text);
    if (!event.data.text.includes("$") && !isNaN(year) && year % 5 != 0)
        event.preventDefault();
});

chart.animate({
    config: {
        "channels": {
            "x": "Year",
            "y": [
                "Revenue [$]",
                "Format"
            ],
            "color": "Format"
        },
        "geometry": "area",
        "align": "center"
    },
    style: {
        "plot": {
            "yAxis": {
                "label": {
                    "numberScale": "K, M, B, T"
                }
            }
        }
    }
});

chart.animate({
    config: {
        "split": true
    }
});

chart.animate({
    config: {
        "channels": {
            "y": [
                "Revenue [$]",
                "Year"
            ],
            "x": [
                "Format"
            ]
        },
        "geometry": "rectangle",
        "align": "min",
        "split": false,
        "sort": "byValue",
        "reverse": true
    }
});

chart.feature('tooltip', true);
